Both 7 arrangements, however, are to a certain extentobjectionable. In the tipping bucket the material contained sets down when the buck 1 et is hoisted, the heavier stones, gravel, and sand sinking to the bottom, whereas the water collects there above. Ifnow the bucket is tipped, the water jumps out and inundates more or less the casting chute, whereas the v of the bucket, and must subsequently be discharged by means of shovels. This veryfrequently results'in interruptions of the operation. It is further objectionable that the one-sided acting charge exerts a very strong pressure on the tipping mechanism upon the tipping of the bucket, so that a correspond ingly strong construction of these elements is required. On the other hand, the buckets having bottom discharge are objectionable as their closure is never completely tight, so that valuable substances, such as cement, are wasted in the form of cement broth, so that the concrete mixture is impaired. The operation of the slide closures of this typerof buckets is further frequently interrupted by the slides being jammed by said grains or little stones. Finally the whole equipment may be soiled by cement broth unless the slide closure is completelytight. V

It is the purpose of this invention to do away with these drawbacks. According to my invention the discharge of the concrete buckets is effected by the tilting of one or a 9 plurality of discharge spouts tiltable around a horizontal axis and being preferably so long that they prevent a discharge of the material from the bucket when being in their upright position. Accordingly the objectionable slide pressures produced by the tipping of they bucket on the other hand, are successfully avoided. The tiltable or rotatable discharge stones, gravel, and sand remain at the bottoml spouts can be supported by the body of the 376941, mid in' Germany m 17, 192s.

So for example locking pawls, counter-weights, automatically acting locking mechanisms or the line devices might be used, as will be readily understood. H

As above mentioned the discharge spouts e are preferably given such a length that a discharge of the material contained in the bucket c is prevented, when the spouts are in their upright position. It is, of course, also possible to carry out the discharge spouts shorter. In this instance suitable slide closures or the like must be arranged in order to avoid an undesired discharge of the ma terial. V V

In the embodiment, Figures 1 to 3, the laterally arranged discharge spouts are only onesidedly supported, WllQlQfl'Olll obj ectionabie stresses or distortions might result upon the discharge of the buckets. This deficiency is avoided in the embodiment, Figures 4 to 6, according to which one or a plurality of discharge spouts canbe' arranged at the central plane of the bucket. In the particular embodiment illustrated in Figures 4: to. 6: one single discharge spout of this. type is arranged and two-sidedly supported in con tradistinction. to the embodiment, Figures 1 to 3, so that the spout may ofier a higher resistance to the strains produced by and upon the discharge of the bucket, and the rotation or tilting of the spout may be efiected easily and without friction or jam= ming. lThese spouts may be arranged at the front or back wall or at the bottom of the bucket. According to requirements one such discharge spout or a plurality thereof may be provided, for example one of these spouts respectively at the front or the back wall of the bucket. at which the discharge spout is attached, is preferably given the discharge spout is attached with a double-sided support and which at the same time acts as a deflector for guiding the'mae terial into the discharge spouts.

According to Figures a to 6 the discharge spout e is arranged at the central plane of rail m cooperating, as the corresponding element of Figures 1 to 3, with a suitable stop or roller arranged on the guiding mast at a suitable point in order to automatically tilt the discharge spout. Also with this embodiment the discharge spout can be given an upward bias, for example by the same means illustrated in Figures 1 to 3.

I claim:

A hoisting mechanism comprising a bucket means for maintaining said bucket in substantially vertical position, a pivoted tubular spout secured to said bucket, said spout serving as anad'diti-onal container when in upright position, and a casting mast, a stop thereomand a guiding rail upon said spout designed to cooperatewith a stop upon the castingmast at the discharge position to tilt said spout downwardly and secure the discharge of the contents of said buckets In testimony whereof I afiiX my signature.
